Uterus: Is it smooth or have assymetrical areas?

An odd question I know, but when you feel your uterus (esp when it gets tight) is it perfectly symmetrical and round or do you have certain areas that are not and come out further? I have one area in particular that comes out a bit further than others. The doc said it's the baby, but that seems weird (though I guess likely true).

There is usually an area above my belly button that sticks out more than normal, especially during a Braxton Hick. From my ultrasounds, I know that it's his butt. He moves around a lot though, so sometimes the lump is somewhere else, or not there at all. Why does it seem weird that it's the baby? Babies have an irregular shape, so it distorts the shape of your uterus. Like pp said, it'll defintely get more pronounced as the baby gets bigger.

I guess I think it's odd because I'll feel active movements of other body parts (admittedly I still can't tell what's what down there!) and yet that area doesn't move as much. Meaning, I'll feel rolls/swirming around, kicks etc. but this area doesn't move that much. I guess if it's the head or butt, maybe it won't? I guess I'm picturing the head and butt moving as much as the other parts, so maybe that's where I'm wrong.

Eh, once they get their butt snuggled up nice and firm they like to leave it there...the rest wiggles plenty without it moving!!!Â Just wait until he/she gets strong enough to poke out an arm or leg and make a lump with it, things look sooooo weird at times!!
